It took a lot of work for the past 30 minutes for me-- LOL
With Lady GaGa retaking number one from Kelly Clarkson, it appears as though the catfight for number one may have only escalated from here. We also this week have incredible debuts from O.A.R, LMFAO, who I heard from from Pitbull's video for "Krazy", Jim Jones, Akon, and even R&B legend Lionel Richie makes a debut as well, as well as Britney's new single called  "If U Seek Amy". I got a feeling that we could see these artists with those big hits make an impact later this year.
